Read Crop,Art,Trim,Bleed Box Dimensions

Currently using v6.0.2

I have the requirement to open an already existing PDF document and determine the sizes of each of the unique CropBox, ArtBox, TrimBox, and Bleedboxes. 
Ive been going through the documentation and using the ExtendedPageDimensions, it seems you can SET all the individual box sizes when creating a new document.  However, I have been unsuccessful in figuring out how to get those dimensions for a document which already exists.  The best I've been able to do is get the Page size (Height/Width), Margins, Body, Edges...  That all was pretty straight forward and simple :-).


Any help would be greatly appreciated.  Thanks in advance.

Hello,

You can read the existing document using the MergeDocument class and read the extended dimensions of the page by casting it to ExtendedPageDimensions.This will work if you already know that the page has the extended dimensions set, otherwise the casting will fail. There is no property as such in the Page.Dimensions that will tell you if the extended page dimensions are set or not. A work around for this would be to put the casting statement in a try..catch block.

MergeDocument document = new MergeDocument(@"c:\documentA.pdf");

ExtendedPageDimensions exp = (ExtendedPageDimensions)document.Pages[0].Dimensions;

Dimensions art = exp.ArtBox;

Please be aware that the MergeDocument class is available in the DynamicPDF Merger not in the Generator.

Thank you very much for the quick reply.

I was able to get the required dimensions by casting the Page.Dimensions to the ExtendedPageDimensions class.  I never thought of trying to do that and it works perfectly!

However, I am encountering an issue with regards to the actual positioning of the said boxes.  As a test I drew a Rectangle on the page over the ArtBox, BleedBox, CropBox, MediaBox, and TrimBox.

My problem is that when I draw these Rectangles they all show up down and to the right of where the artwork really is on the page.  The size of the rectangles seems correct however, which means the bottom-right corner is down and to the right of where I would expect it to be. Hopefully this makes sense, I can e-mail an example attachment if needed to explain more clearly.

This is the code I have for actually drawing the Rectangles on the page.

page4.Elements.Add(new Rectangle(ArtBox.Left, ArtBox.Top,
   ArtBox.Width, ArtBox.Height, RgbColor.Yellow));
page4.Elements.Add(new Rectangle(BleedBox.Left, BleedBox.Top,
   BleedBox.Width, BleedBox.Height, RgbColor.Red));
page4.Elements.Add(new Rectangle(CropBox.Left, CropBox.Top,
   CropBox.Width, CropBox.Height, RgbColor.Black));
page4.Elements.Add(new Rectangle(MediaBox.Left, MediaBox.Top,
   MediaBox.Width, MediaBox.Height, RgbColor.Fuchsia));
page4.Elements.Add(new Rectangle(TrimBox.Left, TrimBox.Top,
   TrimBox.Width, TrimBox.Height, RgbColor.HotPink));


I suspected that the Rectangles may not be 100% perfect because I could not tell if the border size is drawn inside or outside of the extents of the Rectangle.  So they may be 2pix larger.  But in my test they are showing up about .25in low and .125in right of the top-left corner.

Below were the Dimension sizes for each of the Boxes:

ArtBox Height: 648
ArtBox Width: 288
ArtBox Top: 39
ArtBox Bottom: 687
ArtBox Left: 21
ArtBox Right: 309
BleedBox Height: 666
BleedBox Width: 306
BleedBox Top: 30
BleedBox Bottom: 696
BleedBox Left: 12
BleedBox Right: 318
CropBox Height: 708
CropBox Width: 330
CropBox Top: 0
CropBox Bottom: 708
CropBox Left: 0
CropBox Right: 330
MediaBox Height: 708
MediaBox Width: 330
MediaBox Top: 0
MediaBox Bottom: 708
MediaBox Left: 0
MediaBox Right: 330
TrimBox Height: 648
TrimBox Width: 288
TrimBox Top: 39
TrimBox Bottom: 687
TrimBox Left: 21
TrimBox Right: 309
Page Height: 708
Page Width: 330
Page Top Margin: 39
Page Bottom Margin: 21
Page Left Margin: 21
Page Right Margin: 21
Page Edge - Top: 0
Page Edge - Bottom: 708
Page Edge - Left: 0
Page Edge - Right: 330
Page Edge Height: 708
Page Edge Width: 330
Page Body - Top: 39
Page Body - Bottom: 687
Page Body - Left: 21
Page Body - Right: 309
Page Body Height: 648
Page Body Width: 288

Oh, and I apologize for placing this in the wrong forum.

If possible, could an admin place this in the DynamicPDF Merger for .NET (v5.x) forum where it belongs.

Hello,

When considering the Crop, Art, Trim & Bleed boxes, they are considered with respect to the top and left edges of the document. Where as when you add the page elements they are added with respect to the top and left margin of the document.
